Sizewell B nuclear power station on the Suffolk coast has had its second automatic shutdown in four months. Owner EDF Energy said electricity production had ceased at 17:11 BST on Wednesday and it was investigating the cause of the stoppage. A spokesman said: "The reactor was safely shut down, with the plant responding as expected and at no time was anyone's safety at risk." The plant had an 11-day automatic stoppage in March. EDF said it was not predicting when the plant would begin generating again. The company said the March shutdown had been the first automatic one in three years and was for an electrical fault in the non-nuclear side of the plant. There was a controlled stoppage in May to fix a lubrication problem. EDF Energy said Sizewell B produced enough electricity for two million homes, or about 3% the UK's electricity needs.

Is this kind of "automatic shutdown" with cause unknown a common event occurring at nuclear power plants all over the world, but people and the media (like Reuters) have started to pay more attention because of the Fukushima I Nuclear Power Plant accident?

Operators are not going to publicly announce a huge vulnerability to computer viruses like Stuxnet or Flame. NPP computer systems should not be attached to the Internet unless industrial strength firewalls are in place. We heard recently that Flame has been out awhile. Using computer viruses for blackmail or for general mayhem purposes cannot be permitted in nuclear operations. Yet, for defense purposes we have already done this, a serious mistake I think. God speed the firewalls or brace for the conclusions! On a non-hysterical side, these ongoing failures may be due to aging NPP's with failing electrical equipment and PLV's. The fact that these 'unk' failures are not found ahead of time and fixed, tells me that NPP vulnerabilities need to be identified, prioritized by risk, and the money spent, immediately, to secure them.

About my coverage of Japan Earthquake of March 11

I am Japanese, and I not only read Japanese news sources for information on earthquake and the Fukushima Nuke Plant but also watch press conferences via the Internet when I can and summarize my findings, adding my observations.

Well, this was, until March 11, 2011. Now it is taken over by the events in Japan, first earthquake and tsunami but quickly by the nuke reactor accident. It continues to be a one-person (me) blog, and I haven't even managed to update the sidebars after 5 months...
